App1ieation filed June 30,

This inventionrelates to improvements in automatic filling replenishing looms and the object thereof is to provide means for 1nsuring the proper transfer of a fresh filling carrier into the shuttle and the threading of the shuttle upon its first piclcafter the filling carrier has been introduced therein.

fine of the principalfeatures of the invention consists in providing means for guiding the tip of the shuttle during its passage from the hopper into the shuttle.

Another feature of the invention consists in providing means to receive and guide the filling running to the filling carrier, said means preferably being so formed as to draw the thread slightly laterally of the path of the shuttle in such a manner as to insure the drawing of the filling into the thread eye of the shuttle.

Other objects and features of the invention will be more fully described in the following specification and the accompanying. drawings and will be particularly pointed out in the claims.

The drawings illustrate my invention as. applied to a loom of the well known Northrop type.

iVhile the invention as illustrated herein is applied to the well known Northrop type of loom it will be understood that it may Speeification of I zetters Patent. Patrgntgd J i 2"? 1922;

be adapted to other types of looms in which a filling carrier is automatically transferred from a hopper or battery to the active shuttle.

The loom as shown in the drawing comprises the usual frame 1 and breast beam 2 supporting on its end a hopper stand 3 hava rotary hopper 4: provided at its perlphery with recesses to receive a series of fresh filling carriers 5, suitable means being provided for rotating the hopper. The transferring mechanism may be of the usual type comprising a transferrer stud 6 projecting from the hopper stand3 upon which is pivotally mounted the transferrer 7 having the usual transfer head 8 and tip depressing arm 9 provided with a forked end l0 to engage the filling carrier adj acent the tip thereof. The transferrer 7 has the downwardly extending arm 11 to which is pivotally connected a dagger 12 adapted to be engaged by a bunter 13 carried by the lay 14 which is supported upon usual swords and provided with a; box to receive the shuttle 15, these parts being actuated in the usual manner. Inasmuch as the mechanism for actuating the transferring mechanism is old in the art no further description of the same is'nccessary as it will be underd that any usual detecting and controlinechanisin may be, employed.

The present invention consists in providing a guiding means for the tip of the filling carrier, preferably rigidly supported upon the frame of the machine and desirably by the transferrer stud 6. This guiding means overlies the shuttle when in its transferring position and is located closely adjacent thereto so that the tip is guided positively into the proper position inthe shuttle.

In the preferred embodiment of the invention disclosed in the drawing an arm 16 is fixedly secured upon the transferrer stud by one or more set screws 17 and extends downwardly and latterally therefrom, across the path of the shuttle. It preferably has a curved downwardly extending portion 18 provided with upwardly extending ribs 19 providing therebetween a guideway 20 for the tip of the filling carrier. The usual curved tip support 21 may be pivotally mounted upon a stud 22 on the arm 16 to engage the tip of the filling carrier which is in transferringposition. The tip support 21 has the usual shouldered extension 23 which engages a boss 24; on the arm 16 and is held normally in elevated position to engage the tip of the fillin carrier'by the usual helical spring which is mounted upon the stud 22 and enclosed within a barrel 25 surrounding said stud. The tip guiding construction above described positively guides the tip of the filling carrier during its passage from the hopper into the shuttle after it is forced out of engagement with the tip support by the action of the transferrer. This insures accurate positioning of the filling carrier in the shuttle by preventing any possible lateral displacement which might occur by reason of improper positioning of the filling carrier in the hopper or by the action of the yielding tip supporting member 21.

In order to insure the threading of the filling into the eye of the shuttle a filling guide is provided to receive and direct the filling leading to the filling carrier after it is transferred to the shuttle. In the preferred embodiment of the invention disclosed herein the curved downwardly extending portion 18 of the tip guide is provided with a preferably obliquely disposed extension 26 having a slot 27 which inclines rearwardly in respect to the longitudinal axial plane of the loom. This extension may be made in the form of a casting having two parallel members 26 and 28 forming the slot 27; preferably lugs 29 and 30 being provided adjacent the open end or" the slot to provide a restricted opening through which the filling is drawn into the guiding slot 27 to insure the fillingbeing'retained within the slot after it has been once introduced therein. By reason of the fact that this slot inclines slightly rearwardly in respect to the longitudinal axis of the loom the filling running to the filling carrier is drawn slightly sidewise as the shuttle is picked across the lay after transfer. This causes the filling to be more certainly drawn beneath the over-hanging guide of an automatic thread eye so that the filling will be positively and unerringly drawn into the eye of the shuttle.

It will be understood that the embodiment ofthe invention disclosed here is illustrative and not restrictive and that various changes in form, construction, and arrangement of the parts may be made within the spirit and scope of the following claims.

Having thus described my invention, what I claim as new'and desire to secure by Letters Patent, is:

1. In an automatic filling replenishing loom comprising a hopper to support a supply of fresh filling carriers and transferring means, a yieldable support for the tip of a filling carrier when in transferring position and a stationary guide located below said tip supporting means having a slot to receive and direct the tip of the filling carrier presented to it by said yielding tip support during the passage of the filling car rier into the shuttle.

2. In an automatic filling replenishing loom comprising a hopper to support a supply of fresh filling carriers and transferring means, stationary guiding means overlying the transferring position of the shuttle to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, and a filling guiding means carried by said tip guiding means operable to direct the filling latorally of the path of the shuttle, whereby the filling will be effectively drawn into the shuttle eye.

3. In an automatic filling replenishing loom comprising a hopper to support a supply of fresh filling carriers and transferring means, guiding means to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, a stationary arm overlying the transferring position of the shuttle having a guideway to receive and direct the tip of the filling carrier duringthe passage of the filling carrier from the hopper into the shuttle, said arm having an offset extension provided with a slot to guide the filling into the eye of the shuttle.

i. In an automatic filling replenishing loom comprising a hopper to support a supply of fresh filling carriers and transferring means, guiding means to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, a stationary arm overlying the transferring position of the shuttle having a guideway to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, said arm having a slot provided with a restricted opening and operable to receive and guide the filling into the eye of the shuttle.

5. In an automatic filling replenishing loom comprising a hopper to support a supply of fresh filling carriers and transferring means, guiding means to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, a stationary arm overlying the transferring position of the shuttle having a guideway to receive and direct the tip of the filling carrier during the passage of the filling carrier from the hopper into the shuttle, said arm having a rearwardly inclined offset extension provided with a longitudinal slot operable to receive and direct the filling into the eye of the shuttle.

In testimony whereof, I have signed my name to this specification.
